Abstract

The transversal filter is widely used in digital data processing. In this paper, we describe a method for using optically tapped, Bragg cell delay lines to implement a general adaptive linear prediction algorithm. Flexibility is achieved through changing the electronic signals. The implementation is in the Fourier domain so that the wide bandwidth of the Bragg cells can be fully used. A high dynamic range can be achieved because the system is interferometric and linear in light amplitude.
